USS Plunger (SS-2) was one of the earliest submarines of the United States Navy. She was the lead boat of her class and was later renamed A-1 when she was designated an A-type submarine. She is not to be confused with the experimental submarine Plunger which was evaluated by the U.S. Navy from 1898 to 1900, but not accepted or commissioned.
